Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mobile phone protective film processing equipment, specifically to a continuous cutting device for processing mobile phone protective films. Background Technology
[0002] A screen protector, also known as a mobile phone screen protector or phone screen protector, is a thin sheet that is applied to the surface of a mobile phone screen. Its main purpose is to protect the original screen of the mobile phone from accidental damage. The processing of a screen protector requires a cutting and processing device.
[0003] Existing mobile phone screen protector processing equipment lacks continuous cutting capabilities. Many older machines use stamping or single-cutting methods when processing unformed screen protectors, processing only one or a few protectors of a fixed length at a time. After completion, the machine must be stopped for manual loading, positioning, and unloading, resulting in frequent interruptions to the production process, extremely low automation, and significant bottlenecks in production efficiency. From loading and alignment to collecting finished products, almost every step requires manual operation. This is not only slow, but the production cycle is also limited by the workers' skill level and fatigue, making it difficult to achieve 24-hour uninterrupted production and hindering capacity expansion. When multiple products need to be cut, if multiple individual cuts are used, small errors may occur in positioning each time. These errors accumulate, leading to inconsistent widths of different protectors cut from the same roll of material, or dimensional deviations in the same batch of products, thereby reducing product quality.
[0004] Therefore, it is necessary to invent a continuous cutting device for processing mobile phone protective films to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a continuous cutting device for processing mobile phone protective films, so as to solve the problem that the device does not have a continuous cutting effect during use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuous cutting device for processing mobile phone protective films, comprising a processing frame, a back frame, an electric push rod, a movable seat, a cutting blade, a fixed seat, an unwinding roller, and a winding roller. The back frame is fixedly installed on one side of the processing frame. An electric push rod is installed in the middle of the front wall of the back frame. A movable seat is installed on the front side of the electric push rod. A cutting blade is installed below the movable seat. Fixed seats are installed on both sides below the movable seat. The fixed seats are fixedly installed on both sides of the surface of the processing frame. An unwinding roller is installed on the side of the surface of the processing frame near the back frame. A winding roller is installed on the front side of the processing frame. Preferably, the processing frame has several cutting grooves on both sides and in the middle of its surface. The cutting grooves are arranged corresponding to the cutting blades. The cutting grooves are located between two fixed seats and directly below the movable seat.
[0007] Preferably, the output end of the electric push rod is equipped with a magnetic block, and the back of the back frame is equipped with a magnetic sleeve that magnetically matches the magnetic block.
[0008] Preferably, the top of the movable base is provided with a plate, and bolts are installed through the middle of both ends of the plate. Threaded grooves matching the bolt threads are opened in the middle of both sides of the surface of the movable base.
[0009] Preferably, the movable seat has sliders on both sides of its bottom surface, the sliders are located in the slide groove, and the slide groove is opened in the middle of the surface of the fixed seat.
[0010] Preferably, a plurality of cutting blades are provided, and a threaded post is provided in the center of the top surface of each cutting blade. The cutting blades are detachably installed below the movable base.
[0011] Preferably, the movable seat is installed by means of an electric push rod, and the electric push rod pushes the movable seat to move horizontally on the surface of the fixed seat.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This continuous cutting equipment for mobile phone screen protectors achieves efficient and uninterrupted operation through the continuity of the production process. The equipment integrates three major functional modules: unwinding roller, processing table cutting station, and rewinding roller. Raw materials are drawn out from the unwinding roller, precisely cut, and the finished product is immediately wound up by the rewinding roller. These three actions are performed continuously, eliminating the interval time of frequent loading, unloading, and transfer in traditional single-piece processing, making the production process seamless. After a period of manual traction, the subsequent continuous cutting effect is achieved, improving the automation cycle of the cutting cycle and effectively enhancing the continuous cutting efficiency. Moreover, the simultaneous operation of multiple blades can ensure the cutting of multiple screen protectors at one time, while ensuring the consistency of product length and cut, improving product stability. Continuity reduces downtime and improves overall efficiency. Attached Figure Description

Detailed Implementation
[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0016] This utility model provides, for example Figure 1-5 The continuous cutting equipment for processing mobile phone protective films shown includes a processing frame 1, a back frame 2, an electric push rod 3, a movable seat 4, a cutting blade 5, and a fixed seat 6. The processing frame 1 has several cutting grooves 101 on both sides and in the middle of its surface. The cutting grooves 101 are correspondingly arranged with the cutting blades 5. The cutting grooves 101 are located between two fixed seats 6 and directly below the movable seat 4. The back frame 2 is fixedly mounted on one side of the processing frame 1. An electric push rod 3 is located in the middle of the front wall of the back frame 2. A magnetic suction device is installed at the output end of the electric push rod 3. Block 301, the back of the back frame 2 is mounted on the middle of the back of the magnetic sleeve 302 that is magnetically matched with the magnetic block 301, the electric push rod 3 is provided with a movable seat 4 on the front side, the top of the movable seat 4 is provided with a plate 401, the two ends of the plate 401 are both through bolts 402 are installed, the two sides of the movable seat 4 are both provided with threaded grooves 403 that match the threads of the bolts 402, the two sides of the bottom surface of the movable seat 4 are both provided with sliders 404, the sliders 404 are located in the grooves 405, the grooves 405 are opened in the middle of the surface of the fixed seat 6; The cutting power of the equipment comes from the electric push rod 3. After the electric push rod 3 is powered by an external power source, its internal motor drives the push rod to perform precise linear extension and retraction. The extended end of the electric push rod 3 is magnetically connected by the magnetic block 301 and the magnetic sleeve 302, pushing or pulling the moving seat 4 to perform horizontal reciprocating motion. When the moving seat 4 moves, the slider 404 at its bottom is constrained in the groove 405 on the fixed seat 6. This sliding mechanism plays a key guiding and stabilizing role, ensuring that the moving seat 4 and the cutting blade 5 below it always move along a precise and stable straight path, preventing deviation or shaking during the cutting process, thereby ensuring a straight and smooth cut. A cutting blade 5 is provided below the movable seat 4. Several cutting blades 5 are provided. A threaded post 501 is provided in the middle of the top surface of the cutting blade 5. The cutting blade 5 is detachably installed below the movable seat 4. Fixed seats 6 are provided on both sides below the movable seat 4. The fixed seats 6 are fixedly installed on both sides of the surface of the processing frame 1. The movable seat 4 is connected and installed by an electric push rod 3. The electric push rod 3 pushes the movable seat 4 to move horizontally on the surface of the fixed seat 6. A unwinding roller 7 is provided on the side of the surface of the processing frame 1 near the back frame 2. A winding roller 8 is provided on the front side of the processing frame 1. Multiple cutting blades 5 are mounted and fixed to the bottom of the movable base 4 via threaded posts 501 on their tops. When the electric push rod 3 pushes the movable base 4 forward, all the cutting blades 5 press down synchronously, like multiple paper cutters, cutting the protective film material passing underneath. The cutting depth of the blades is controlled by the settings of the equipment, and finally cuts into the pre-set cutting groove 101 on the surface of the processing frame 1. The function of the cutting groove 101 is to provide cutting space, avoid direct collision between the blade tip and the hard surface of the processing frame 1, protect the blades, and ensure that the blades can completely cut the protective film without leaving any connecting ribs due to the support of the surface. The unwinding roller 7 is loaded with the wide roll of protective film raw material to be cut. The take-up roller 8 is driven by an external power source and rotates at a constant speed to generate traction force. The material is drawn out from the unwinding roller 7, spread flat over the surface of the processing frame 1, passes under the cutting blades 5, and finally winds onto the take-up roller 8. The continuous rotation of the take-up roller 8 realizes the intermittent or continuous feeding of the material. The working principle of this practical application is as follows: Refer to the instruction manual appendix Figure 1-5For this type of continuous cutting equipment for mobile phone protective film processing, the cutting power of the equipment initially comes from the electric push rod 3. After the electric push rod 3 is powered by an external power source, its internal motor drives the push rod to perform precise linear extension and retraction. The extended end of the electric push rod 3 is magnetically connected through the magnetic block 301 and the magnetic sleeve 302, pushing or pulling the moving seat 4 to perform horizontal reciprocating motion. When the moving seat 4 moves, its bottom slider 404 is constrained in the groove 405 on the fixed seat 6. This sliding mechanism plays a key guiding and stabilizing role, ensuring that the moving seat 4 and the cutting blade 5 below it always move along a precise and stable straight path, preventing deviation or shaking during the cutting process, thereby ensuring a straight and smooth cut. Multiple cutting blades 5 are connected by threaded posts 501 at their top. Mounted and fixed at the bottom of the movable base 4, when the electric push rod 3 pushes the movable base 4 forward, all the cutting blades 5 press down synchronously, like multiple paper cutters, to cut the protective film material passing underneath. The cutting depth of the blades is controlled by the settings of the equipment, and finally cuts into the pre-set cutting groove 101 on the surface of the processing frame 1. The function of the cutting groove 101 is to provide cutting space, avoid the blade tip from directly colliding with the hard surface of the processing frame 1, protect the blades, and ensure that the blades can completely cut the protective film without leaving any connecting ribs due to the support of the table. The unwinding roller 7 is loaded with the wide roll of protective film raw material to be cut. The take-up roller 8 is driven by an external power source and rotates at a constant speed to generate traction force. The material is drawn out from the unwinding roller 7, spread flat over the surface of the processing frame 1, passes under the cutting blades 5, and finally is wound onto the take-up roller 8. The continuous rotation of the take-up roller 8 realizes the intermittent or continuous feeding of the material. When using this device, the large roll of protective film raw material is installed on the unwinding roller 7, the end of the material is pulled out and laid flat on the table of the processing frame 1, and passed between the two fixed seats 6, that is, below the moving seat 4 and the cutting blade 5, and finally fixed on the take-up roller 8. According to the required width specifications of the product to be cut, the position and number of the cutting blades 5 on the moving seat 4 are adjusted, the nuts fixing the blades are loosened, the blades are moved to the position of the corresponding cutting groove 101 and then locked. The arrangement of the cutting grooves 101 provides a positioning reference for the width. After the equipment is in use, the cutting blades 5 are detachable. When the blades are worn and dull, they can be removed from the moving seat 4 for replacement or grinding simply by unscrewing the fixing nuts, which is very convenient for maintenance.
